摘要:用微波辐射乳液聚合的方法，合成甲基丙烯酸甲酯、丙烯酸丁酯与甲基丙烯酸六氟丁酯的三元含氟乳液纸张施胶剂，并通过表面涂布的方法对纸板进行施胶。探讨乳化剂用量、微波辐射时间和含氟单体用量对产率以及表面施胶纸板防水性能的影响。结果表明，微波功率为50 W的条件下，乳化剂用量为3%、含氟单体用量为10%、微波辐射时间为4.5 min时，产率能达到90%以上，当涂布量为0.9 g/m2时表面施胶纸板的接触角能达到121°，Cobb值能达到14 g/m2。
Abstract:The paper sizing agent was synthesized by emulsion polymerization of methyl methacrylate, butyl acrylate and hexafluorobutyl methacrylate under microwave irradiation. Paper board was sizing by coating the sizing agent, and then the waterproof abilities of the coated paper board was characterized by measuring the contact angle and Cobb value. The effects of the dosage of emulsifier, microwave irradiation time and the amount of fluorinated acrylate on productive rate and waterproof performance of the coated paper board were studied. When the microwave power was 50 W, emulsifier dosage was 3%, fluorinated monomer dosage was 10% and microwave irradiation time was 4.5 min, productive rate was more than 90%, the contact angle and the Cobb value of the coated paper board could reach 121° and 14 g/m2 respectively.
